' SPRINKLER-HEAD.

Specification of Letters Patent.

Patented July 26, 1921.

Application filed June 30, 1920. Serial No. 392,942.

To all whom it may concem.

Be it known that I WILLARD CLARKE PENTY, a citizen of the llnited States, and a resident of Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements n Sprinkler-Heads, of which'the followlng 1s a ecification.

y invention relates to spr nkler heads employed in automatic sprinkling systems, and a purpose of my invention is the provision of a sprinkler head which is soconproper spreadmg and falling of the water on al parts of the area allotted for fire protection by the particular valve. Furthermore, my invention allows a uicker and more efficient ad ustment of the valve and prevents leakage of water from the head, the sprinkler head being capable of quick assembly to facllitate installation.

I will describe one form of sprinkler head embodying my invention and will then point out the novel features thereof in the claim.

In the accompanying drawings:

Figure 1 is a perspective view showlng one form of sprinkler head embodying my invention in locked position.

Fig. 2 is a central vertical sectional view of the sprinkler head shown in Fig. 1.

Fig. 3 is a view showing in sect on one of the water supply pipes of a sprinkling system having applied thereto the sprinkler head shown in the preceding views, the latter being in released position.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawm s, A designates a short section of pipe or s eeve formed adjacent its upper end with an annular head B. Below the head B the outer surface of the sleeve A is screw threaded to permit of its ap lication to the water sugply pipe of a sprink ing system, as shown 111 1g. 3. The sleeve A within the head B is formed to provide a valve seat C upon which reposes a rubber gasket D. Adapted to seat upon the gasket D is a valve E which is of a diameter corresponding to that of the seat C so as to completely close the upper end of the sleeve A.

The head B carries a substantiall U- shaped yoke designated generally at and which comprises a stationary sectlon 15 and a movable section 16. The stationary section 15 is formed integral with the head B and constitutes a major portion of the yoke, as w ll be understood from a consideration of Fig. 3. The section 15 carries adjacent its free end a deflecting cap G which, as shown, 18 of concaved formation and formed with a fluted edge. The cap G is detachably associated with the section 15 by means of a screw H which, as shown in Fig. 2, is threadedly fitted within suitable projections formed on the inner side of the sections. The movable section 16 is hingedly supported upon the cap B by means of a pin K which extends through a suitable recess formed in the periphery of the pin and through a projection 16* formed on the end of the section 16. The section 16 carries intermediate its ends a laterally extending arm 16 which, in the locked position of the yoke, is adapted to overlie the valve in the manner shown in Figs. 1 and 2. Threadedly fitted within the arm 16 is a set screw L, the lower end of which normally engages the valve E and is disposed within a suitable recess formed in such valve thereby effecting a locking of the valve against displacement from the seat C.

The confronting ends of the sections 15 and 16 are preferably formed with an interfitting connection which as illustrated to advantage in Fig. 1 comprises a tongue 15 formed on the end of the section 15, and a groove 16 formed-on the end of the section 16 and of a contour to receive the tongue.

Because of the manner in which the section 16 is pivotally supported upon the head B, it will be clear that such section normally tends to ravitate to the position shown in Fig. 3. fiowever, the sectlon 16 is normally locked in the position shown in Fig. 1 by means of a bar M which is supported upon studs S in a manner to ri idly connect the two sections and retain t e same in yoke formation. The bar M is formed of any fusible substance such as lead or the like and is removably fitted upon the studs S so as to permit the ready substitution of a new bar when. the first bar is disrupted.

In the applied position of the sprinkler head to one of the nozzles of a sprinking system, the parts of the head normally occupy the positions shown in Figs. 1 and 2.

he pressure of Water bearing against the valve E is ineffective to remove the valve from its seat by virtue of the set screw L, it being understood that the adjustment of the screw is such as to securely hold the valve upon its seat, thus preventing the sequently released and under the pressure of water acting onthe valve E, is thrown to the position shown in Fig.3, 'As the'section 16 remains in this released position, the

I valve'E'is projected from its seat, thus allowing the water to be discharged through the sleeve A and into contact with the ca G. Beca'use of the curvature of the cap, it

' will be clear that the'water is deflected downwardly in all directions, so as to spray all parts of the allotted area, and to thereby effectively extinguish any and all fires Within such area; 1 7

Although I have herein shown and described only one form of sprinkler head embodying my invention, it is to be understood that various changes and modifications may When the bar M is" be made herein without departing from the spirit of the invention and the spirit and scope of the appended claim.

What I claim is:

A sprinkler head comprising, a threaded sleeve having a valve seat formed at one end thereof, a head formed on said sleeve, a yoke carried by said head and comprising a stationary section fixed to the head and a movable section hingedly supported on said head for an outward swinging movement from the stationary section, said sections having interfitting ends, a deflecting cap carried by the stationary section and overlying said valve seat, a valve normally reposing on said seat, an arm formed on the movable section, a set screw adjustably mounted on said arm and engageable with said valve for retaining the same on said seat, studs formed on said sections, and a fusible bar removably fitted on said studs ands anningsaid sections for the purpose descri ed.
